Native Oyster (Ostrea edulis) Restoration Salacia-Marine have been involved in native oyster studies for some time and most recently have led on the at sea monitoring at the Mumbles Oyster Company Ltd.'s restoration project in Swansea Bay.  This project set out to establish whether the derelict beds at Mumbles and the wider Swansea Bay population could be restored by the introduction broodstock oysters.  This project has been a great success with the introduced broodstock oysters surviving the worst winters in 50 years to reproduce the following summer.

Salacia-Marine have been advising Blue Marine Foundation and the stakeholder group in the Solent on the development of a programme of native oyster restoration.  This work has resulted in a "vision" document and the development of a number of restoration collaborations with local businesses and institutions.

Blue Marine's Vision for the Solent

Ecosystem niche review for species caught by commercial potting (Natural England) This project reviewed the respective ecosystem niche that crustacean and molluscan species targeted by commercial fisheries within English waters and MPAs occupy.  Developing a common understanding of their role in ecosystem function will help managers understand what, if any, effect that removing them would have on the ecosystem functioning of the designated features or habitats.  It resulted in an extensive literature review and an MS Access database search tool for the end user.

Inshore Vessel Monitoring Systems and Data Recording (Welsh Government/Succourfish) Salacia-Marine are providing liaison and co-ordination for a trial of iVMS and the Catch App.  This short project aims to trial and demonstrate the data collection potential for fishermen data collection in Wales.  The Catch App enables individual fishermen to accurately record catch data and discards alongside their GPS positional data to produce an un-paralleled high-resolution dataset of fishing activity.

Lyme Bay Fisheries and Conservation Reserve Project (Blue Marine Foundation) Salacia-Marine are providing fisheries and conservation management advice to the Lyme Bay project.  This project aims to develop and implement best practice in fisheries and conservation management with a highly sensitive site.  Seen as an example of best-practice in co-management of fisheries and conservation management in MPAs, this project is developing some important research and practical solutions that aim to enable traditional fishing activities to continue and conservation objectives to be met.  These include:

Fully Documented Fishery Project Fully Documented Fishery Project which aims to collect fishing activity from the whole fleet of under 10-metre by trialling Succourfish iVMS equipment alongside a novel iPad based Catch App that enables fishermen to collect catch data including discards.  This is seen as a step beyond using iVMS for a purely monitoring tool for managers and the development of a dataset that could transform inshore fisheries and conservation management.

Native Oyster (Ostrea edulis) Studies We have been working on a series of studies investigating the current status of the native oyster in South Wales.  These have included a series of video surveys of historic beds, MSc projects undertaking population surveys and a substantial review of native oyster restoration options for Wales.

Restoration of Native Oyster Ostrea edulis in South Wales Options and Approaches Report

Video Surveys of Historic Native Oyster Beds in South Wales (CCW) Using Salacia-Marine's video survey sledge we have carried out extensive surveys of historic native oyster beds off Tenby, Caldey Island, Stackpole and St Govan's Head.  Further surveys have been carried out in and around Swansea Bay.  These surveys were informed by 90 year old records, fishermen's Local Ecological Knowledge and acoustic data from commercial fishing vessels. This survey information will inform projects to restore native oyster beds.

Cockle Mortality Monitoring in the Burry Inlet and Three Rivers Estuaries The cockle population in these estuaries have suffered regular summer mortalities since 2002. Managers and industry stakeholders required timely assessments of cockle beds and progression of mortality. We developed assessment approaches and a monitoring programme to inform managers and fishery stakeholders.

Review of Cockle Management in the Burry Inlet (on behalf of the SAGB for the Environment Agency) Fishery managers of the cockle fishery in the Burry Inlet urgently required advice on the evidence base for current and potential management actions. SAGB were approached and we carried out a review and provided advice.

Shellfish Health and Nutrition Project (SAGB) This is an extensive literature review that aims to identify all the health and nutritional benefits of UK shellfish. The resulting reports included, in addition to a scientific and technical text, an easy to follow 'lay-person' summary.

Adaptive management protocol (SAGB/Seafish/NE) This project developed an adaptive management protocol for shellfisheries operating in SACs and SPAs.  The protocol has been successful in enabling shellfish farm developments to gain consents within sensitive sites by addressing the precautionary principle with risk-based mitigation and adaptive management approaches.  The protocol is seen as a key tool in site management enabling sustainable development whilst affording protected features the legally required level of protection.

Fishing activity/effort mapping of shellfish fisheries (SAGB) This major project draws on examples of fishing activity mapping from around the world to develop a rapid approach to map the activities of the shellfish fishing sector. Central to this approach is an effort proxy to enable the application of value multipliers. Two trials have taken place, a static gear fishery off Eastbourne and a mobile scallop fishery in West Wales.

Statistical analysis of fishing vessel statistics and spatial data (Sussex SFC). This brief study investigated the links between vessel size, power and fishing method with distances travelled from home port. This information may be important in determining each ports zone of influence for MCZ and spatial planning.

National Shellfish Resource Group (NSRG) - Scoping Study This study was undertaken for the Shellfish Industry Development Strategy at the Shellfish Association of Great Britain to develop a scientific and technical support structure for shellfish managers. The report describes the requirements of managers and provides a framework to address these needs. A pilot project is likely to be run in the near future.

National Shellfish Resource Group (NSRG) - Scoping Study

Fishing Activity Mapping in South Wales (SWWFC Ltd) This short study aimed to record the variety and spatial extent of fishing activities in the South West Wales Fishing Communities district.

Fish recording project (CCW, WFFA). This project aims to enable fishermen (commercial and anglers) to record sightings and records of fish species around the Welsh and UK coasts. Linking to a soon to be published ID guide the project recording website based at Marlin in Plymouth employs a variety of technologies to record accurate locational and species data. The data will eventually be available through the National Biodiversity Network.

Development of a Sediment Monitoring Protocol for shellfish farmers. This short study developed a basic sediment monitoring approach to enable shellfish farm operators to provide environmental information as part of an adaptive management plan.

Addressing the common information gaps delaying environmental assessment of shellfish farm developments. This is a two stage project:

·   A consultation of nature conservation agencies, fishery managers and consenting authorities.

·   The development of Standard Operating Procedures to enable industry operators to gather basic environmental information to inform environmental assessments.

Information Shortfalls Affecting Assessment of Shellfish Farm Projects Report

Standard Operating Procedure development. This project developed a series of intertidal and subtidal habitat mapping methodologies to enable fishermen and shellfish farmers to undertake basic habitat surveys. These were trialled in a series of case studies using a variety of photographic and underwater techniques. These approaches have been accepted by Natural England, CCW and other conservation agencies as appropriate techniques to provide habitat information to inform site management.

Collation of shellfish data to inform the development of CCW bird prey model (CCW) This brief study collated fisheries data from a variety of sources including paper records of landings, fishery officer reports and field surveys.

The development of 'Environmental Best Practice' guidelines for fishermen considering the development of a new fishery (Seafish). This project included a case study into the development of a Razor Clam (Ensis spp.) fishery in an area adjacent to a European Marine Site. This document can be applied to a variety of fishery developments when they may take place inside or adjacent to a protected site.

'Environmental Best Practice' guidelines

Assisting the mussel cultivation sector developing a code of practice to reduce the risk of the spread of non-native species. The aim of this project is to develop preventative measures to ensure the spread of non-native species such as Slipper limpets (Crepidula fornicata) and to develop monitoring protocols to provide early warning in the event of transport.

Investigation into an on-going mortality of Cockles in the Burry Inlet and Three Rivers estuaries (Bangor University).  A data collation and analysis project based at Bangor University with the aim of focusing future investigation into the on-going mass mortality of Cockles (Cerastoderma edule) in the MSC accredited Burry Inlet fishery.

Electrofishing for Razor Clams (Ensis spp.). This project aims to develop an environmentally more acceptable method for harvesting Razor Clams (Ensis spp.) than the currently used hydraulic dredge. Our role is the provision of independent scientific and technical advice.
